[PATCH v3 3/4] dt-bindings: gpio: fsl-imx-gpio: add gpio-line-names

Describe common "gpio-line-names" property to fix dtbs_check warnings
like:

  arch/arm/boot/dts/imx53-m53menlo.dt.yaml: gpio at 53f84000:
    'gpio-line-names' does not match any of the regexes: '^(hog-[0-9]+|.+-hog(-[0-9]+)?)$', 'pinctrl-[0-9]+'
